This study is defined within the context of the critical posthuman project of decentring humanist subjectivity. We argue that because agential realism, and the agency and performativity that go with it, do not enable non-human matter to be accountable, only human matter, in its intra-active becoming with non-human matter, can support an ethical project. Secondly, we map our understanding of Barad’s agential realism, explaining the importance of agential cuts in phenomena-in-their-becoming that are the world worlding itself, and evaluate ethics, agency, (...) and performativity in this material-discursive framework. Thirdly, understanding the material-discursive to underpin storied matter, we engage it via some clarification of narrative, and narrative agency. We conclude that much organic or inorganic nature as non-human matter is directional and responsive, so alive and generative and, in this sense, capable of worlding itself. However, it does not tell its own stories in the process. (shrink)
